Thanks for the help. I tried importing just the Organizations (only 30 entries) and it took them, but as you said, didn’t recognize them as organizations. Then I tried the 1,000 entry list and after a few minutes I got the same error as before (500 Internal Server Error). I need to get this done, so I think I’m going to start over with the old plugin and just divide up the files into six groups of +/-200 — unless you have another suggestion. It’s not ideal, but I think it’ll work.
